A) A and B will represent cooling curves of water and oil respectively
B) B and A will represent cooling curves of water and oil respectively
C) their cooling curves will be identical
D) None of the above
Correct Answer: A
Solution :
We know that, Rate of cooling \[\propto \frac{1}{C\text{ (}specific\text{ }heat)}\] Since \[{{C}_{oil}}<{{C}_{water}}\] (given) \[\therefore \] Rate of cooling of water < Rate of cooling of oil. It is clear that at a particular time after start cooling, temperature of oil will be less than that of water. So, graph A represents the cooling curve of water and graph B represents the cooling curve of oil.You need to login to perform this action.
